" Be it known that l, HARRY FRANKEL, a citizen of the United States, residing in the city, county, and State ol N ew York, have invented certain new and useful Improvements in Splicing-Sleeves, of which the t'ollowing is a full, clear, and exact description.

My invention relates to improvements in splicing sleeves for wires and the like, and is particularly useful when employed for the pur ose of mending broken trolley wires.

Tr is invention is essentially an improvement 1umpon the splicing sleeve made the subject mattei' of my former patent No. 861,717 of JulyO, 1907, and consists broadly in imroved means forclenching the splicing meinlier upon the wire ends so to resist to the utmost degree any slippage between the parts.

'ln the drawings, Figure 1 represents my invention as applied to a broken trolley wire,

said view being a side elevation and showing i an approaching trolley wheel. VFig. 2 is a relatively enlarged longitudinal section, one i end of thc splicing sleeve and trolley wire being removed. Fig. 3 is a side elevation of one of the parts detached. Fig. Ll is an end view oi" the arts shown in Fig. 3 looking from right to elt. Fig. 5 is a view ol another detail of construction detached.

1#1 represents two ends of a trolley wire. represents a trolley wheel bearing against the wire in the usual manner. In Fig. l the splicing` sleeve is shown in ilace, holding the two wire endsv in secure em race. The splicing sleeve comprises the .main body 3 of tubular form, the passage therethrough being arranged to receivi` the two end pieces @lr-f4 which constitute. the` clamping members.

Each end piece e has external screw threads i 4, The bore ol' the main body ol the sleeve is threaded at 3 to receive the threaded portion oi ear-h clamping sleeve. Beyond the threaded portion the bore is somewhat conas l may term them, t rings, the ends of said Vtracted or inclined to l'orni a bearing surface I to receive the jaws file-4 ol' the sleeve so E that when said sleeve is screwed in, said jaws will be drawn toward ear-h other.

4&4? are split rings arranged within tho jaws L.lL-Ll" and around the nrssage therej through, the function ot each ot said split j rings boing to cut transversely into the .metal i ing member adapted to the tapered portion ol the wire end standing within the clamping member. Any desired number ol' these split rings nav be employed to guarantee against all pessioiliiy ol any rain that would occur in use. The inner wall of each jaw is slightly i recessed so as to afford a seat for each split ring Llc-4c.

From the foregoing it follows that 'when the end of a wii'e is slipped through a clamping member and through the split rings cai'- ried by the jaws thereof, the user has but to rotate the parts so as to draw the clamping member into the sleeve, whereupon the jaws lb will be contracted and the retaining device or devices 4C will be caused thereby to cut or score into the surface of the wire to be held, thereby interlocking the parts, thus suppleinenting the frictional clamping action of the jaws to such an extent as to make a joint of the greatest possible strain resisting capacity.

The ends of the sleeve and each clutch member should be appropriately formed, as by a taper in the present instance, since itis necessary foithe proper guidance of the trolley wheel that an easy incline be afforded across which said wheel must travel.

As in my former patent, any suitable tool may be employed for rotating the several parts-during the turning up operation. It may here. be said, as in my former patent, that in some cases it is preferable that the external or exposed surfaces of the several parts be smooth as distinguished from angular or broken.

Nhere the wire scoringl anchoring devices? are in the form of split rings should be spaced erinit said rings to be compressed sufficient y to cut into the metal of the wire. rlhe cutting depth of the split ring anchoring devices may be varied according to the depth of the grooves within the jaws 4b, said grooves being of such a depth as to permit onlyl the desired projection ol: the wire.

lllhile l have shown my improvement in the preferred forni, obviously many changes may beinade without departing from the spirit or scope of this invention.

What l claim is:

1. ln a splicing sleeve for wire and the like,

apart adequately to l a main body portion, a passage therein, a

screw thread in said passage, an inclined oi tapered portion beyond said screw thread, a removable clamping member, a yielding clamping aw at the inner end of said clampolI the sleeve, an intermediate threaded portion on said end piece adapted to the screw threaded portion of the sleeve, anchoring means carried by the clamping jaw at its inner side arranged to score into the Wire to be secured thereby.

2. In a splicing sleeve for'wire and the like, a main body portion, a passage therein, a screw thread in said passage, an inclined or tapered ortion beyond said screw thread, a removab e clampin member, a yielding clamping j aw at the inner end of said clamping member adapted to the tapered portion of the sleeve, lan intermediate threaded p0rtion onnsaid end piece adapted to the screw threaded portion of the sleeve, anchoring means carried by the clamping jaw at its inner side arranged to score into the Wire to be secured thereby, said. anchoring means comprising a split ring arrangedwithin the jaw end ofthe clampin member.

3. In a splicing Steeve for Wire and the like,

.a main -body portlon, a passage therein, a

screw thread in said passage, an inclined or tapered portion beyond'said screwvthread,`a

threaded portion of the sleeve, anchoring means carried by the clamping jawat its inner side arranged to score into the Wire to be secured thereby, said jaw end being recessed internally to carry said ancliorin means, the Walls of said recess preventing t e displacement thereof relatively to the clamping member. l HARRY FRANKEL.
